Which is the town of "Zanzire, Poland"? #belarus #poland

Roy Ogus

On the Ellis Island passenger list for a relative arriving in New York in 1920, he listed his former residence as "Zanzire, Poland."
Does anyone have any idea to which town this may refer?  I had believed that this person had come from one of the towns in western Belarus, likely Dyatlovo/Zhetel or Novogorodok, but the ShtetlSeeker couldn't find anything nearby for the town of "Zanzire".
Thanks for any help.
